The ace leg spinner Bhayanak singh bedi had 1200 runs taken of him in a certain number of matches. In the next match he took 4 wickets conceding 144 runs as a result of which his average (runs conceded / no. of wickets taken) increased by 1. How many wickets did he take before ths last match?
The wickets taken in the last match= 4
Let the number of wickets taken before the last match be X
Then total wickets taken after the last match= X+4
His average after last match= 1
So
1344/(4+X)=1
1344= X+4
X=1340
So the total number of wickets before the last match is 1340
